This cello piece really speaks to me

This piece of music really speaks to me, in every level. I was taught by my music teacher once that the violin is the closest to the human voice, or did he say strings instruments? In either case, the cello then is closest to the speaking human voice. When I listen to this piece, I feel like a good friend is seated with me and talking me. Depending on my different moods, he could just chatting or he could be counseling me, advising me or simply telling me his story. 

I have played the cello back in my school days. Wished I had reached the proficiency to play this amazing piece by Bach.
